Log Read Rate

The R/s dataflow depicts the rate at which the logger is reading log records from disk to memory during database recovery.

Required monitor switch


Displayed statistic

At each refresh, Spotlight captures the number of log reads per second at the database or partition level and displays it just above the read rate dataflow. You can use the Metric Editor to customize thresholds for the metric behind this statistic to generate appropriate alarms.


The line graph that overlays the dataflow plots the log read rate captured over the series of refreshes that have occurred during the Spotlight session.

You can adjust the thresholds for the metric behind this graph to generate appropriate alarms. Additionally, by default, this metric uses a moving average to plot graph points. You can adjust the moving average formula or turn this feature off for the metric.

Use the Metric Editor to modify the thresholds or moving average for the metric behind this graph.

Associated drilldown
